Shibutami lived the life of an everyday high school boy, but with one chronic problem: He could never stay interested in his girlfriends. However, when Yoshizumi transfers into his class, the teenager's arrival strangely piques his interest. Yet, for some reason Yoshizumi seems awkward, even hostile, when Shibutami tries to be his friend. Meanwhile, another high school student with a mask fetish falls deeply in lust with his dentist during an appointment. In another part of the city, a man grows jealous of his own lover's best friend. And elsewhere, a young couple nearly breaks up because they can never agree who should be on top in the bedroom.
